Beit known that I, IRA. A. BLOOD, a citizen of the United States, residing at M ethuen,

in the, county of Essex and State'of Massachusetts, have invented'a'new and useful Improvement in Spool Gluing and Assembling Machines, of which the following is a specification.

This invention has reference to an improvement in bobbin gluing and assembling machines adapted for gluing the heads of spools and assembling the spools by screwing the ends of the spool-cylinders.

In the process of manufacturing wooden spools the heads on the ends of the cylinders have heretofore been glued by hand and the cylinder and heads assembled to form a complete spool by screwing the heads onto the ends of the cylinder by hand. This method of'gluing and assembling the spool by hand is slow, laborious, and expensive to the manufacturer;

The objects of my invention are to glue and assemble spools more expeditiously and at a lower cost than has heretofore been done, and I accomplish these objects by providing a machine that will feed and glue the spoolheads automatically and assemble by screwing the glued heads onto the ends of the spool-cylinder to form a complete spool by the single operation of a lever.

My invention consistsin the peculiar and novel construction of a sembling machine .ada

feed and glue the hea s the cylinder and heads spool gluing and asted to automatically of spools, and when are placed in their proper position in the machine by the olperued. for convenience of construction. be secured together and to the spoo gluing and assembling machine, 'showmg the gluing mechanism in the position it would assume in gluing the heads of a spool and the assembling mechanism in the posi- 1 tion for assembling by screwing the heads lSO onto the ends of a spool-cylinder, (shown in broken lines.) Fig. 2 is a top plan view of the machine with the operative parts in the same position as shown inFi 1. is an enlarged detail sectional V16W taken on Fig. 3

line X X of Fig. 1 through the hopper, showing themeans for adjusting the hopper for different sizes of spool-heads. Fig. 4 is a vertical transverse sectional View taken on line Y Y of Fig. 1, showing the feeding and gluing mechanism operatively connected with the assembling mechanism. Fig. 5 is an enlarged detail sectional view through the spool-head-feed mechanism, showing a feedslide in its normal or outward position. Fig. 6 is an enlarged transverse sectional view taken on line Z Z. of Fig. 1 through the glue-pot, showing the glue-cups in the positionthey would assume in gluing the heads in full lines and the osition they would assume in the glue for ifiling the cups with glue in broken lines. Fig. 7 is an enlarged sectional view of one of the glue-cups, showing the outlet-holes in the side of the cup and the means for securing the cups to the supportin -frame;' and Fig. 8 is a sectional view ta en lengthwise through a completed spool. In the. drawings, a indicates the double frame; I), the gravity-hopper for the SPOOI- heads; 0, the spool-head-feed mechanism; (1, the spool-head-gluing mechanism; e, the actuating mechanism for the feed mechanism c and the gluing mechanism (1; f, the glue-pot; f, the glue in the glue-pot g, a gasburner; h, the head-stock of the assembling mechanism; 11, the tail-stock; k, the releasearm; Z, the operating-lever of my improved spool gluing and assembling machine, and m a spool consisting of the cylinder m, having the longitudinal hole m the screw-threaded ends m m and the circular heads m M having the central screw-threaded h oles m m The double frame a is formed in two parts They may floor, if required. The part 0/ consists of a bed a, supported on the four legs u e as shown in Figs. 1 and 4. The bed a has the closed top a, in which are the longitudinal slotsa a, in the edge of which are the ways a a for the feed-slides, the two circular holes a a for' the glue-cups, and the apertures a a for the frame of the glue-cups, as shown in Fig. 6. A portionof the top a is formed into the removable cover (1 secured to the frame by the thumb-nut bolts 03 a These bolts are pivotally' secured to the cover and engage with the bifurcated lugs a a) on the side of the frame (L as shown in Figs. 1 and 4. The shelves (1 e are formed on the inner face of the bed a to support the glue-potf under the top a and the cover a"; as shown in Fig. 6. On the two. inner legs a a are formed the bearings e e and on the two outer legs a a the bearings a a, and a, a, as shown in Figs. 1 and 4. The part al of the frame a consists of a bed 0, having the ways a" a" and supported on the four legs a a, as shown in Figs. 1 and 4.

The gravity-hopper b for holding the spoolheads m m and supplying the same to the feed mechanism a by gravity consists of an inverted-U-shaped frame I), having the two openings b b in the top and secured transversely to the top a by the bolts b 12 as shown in Fig. 2. The two rods b 5%, having the enlarged heads b 5 aresuspended from the top of the frame I) through the openings 6 b by the heads 1) b These rods extend downward through the holes m m in the heads, the ends of the rods entering the next to the bottom heads, as shown in broken lines in Fig. 5, leaving the bottom heads free to be removed in succession by the feed mechanism 0. A cross-bar b having tneslots b" If, is secured to the back of the frame 1) adjacent the bottom by the bolts?) 11 as shown in Fig. 3, and the wings I) b are adjustably secured to the inner face of the bar I) by the bolts 6 b through the slots 1) b in the bar. An adjustable bar I), having the L-shaped ends I) 5 in which are the slots b" 71 is adjustably secured on the front of the frame I) opposite the bar I) by the bolts 1) I) through the slots b b. By this construction the hopper b is 'made adjustable for different size heads and for centering the heads.

The feed mechanism 0 consists of the two slides c a, each constructed to reciprocate in the ways a a in the openings at a under the slide-heads m m, as shown in Figs. 2 and Each slide has the inwardly-extending tongue 0 bearing on the top a of the frame and constructed to have the steps 0 and a, forming the end 'chand-the shoulders c 0 A yoke c is secured transversely above the ends 0 c of the slides-to the top a? by the bolts 0 c". The bow-springs 0 0 are secured at their center to the yoke 0 the free ends of the springs bearing on the spool-heads, and the whipsprings c c are secured at their fixed ends to the bar I), the free ends bearing on the spool-heads. The guides c c" are adjustably secured to the cover a by the bolts 0 '0 in a position to guide the spool-heads and bring the holes m m in the heads over the circular holes a a in the top of the frame for gluing the holes in the heads. By this con-. struction the spool-heads are fed to the gluing mechanism (Z by the operation of the slides c c. A forward movement of the slides carries the spool-heads from the hopper b under the springs 0 and 0 the tension of I Fig. 6.

the springs being suflicient to hold the heads on the return movement of the slides.

The gluing mechanism (1 consists of a frame constructed to have a cross-bar d, with the bosses d d under the top a in the glue-pot f, the ends (1 d of the cross-bar extending upward through the apertures a a in the top a, the outwardly-extending portions (1 cl and the downwardly-extending arms (1 d all formed integral, as shown in The arms (1 d are further supported and guided by the straps d (1 secured to the sides of the frame (1 The glue-cups d (1 each have the circular cup-shaped head 61 the a ertures d d inthe side of the head, the circu ar flange (1 and the downwardly-extending stem (1, secured to the cross-bar d through a hole in the boss (1 by the set-bolt d", as shown in Fig. 7. A downward movement of the arms (1 d lowers the cross-bar d with the glue-cups d d into the glue, as shown in broken lines in Fi 6. An upward movement of the arms 5 d raises the cups filled with glue through the, circular holes a a in the top a and into the holes m m in the spool-heads m m*, as shown in full lines in Fig. 6. The glue is thus deposited on the surface of the screw-threaded holes m m in the bobbin-heads, assisted by the apertures d d in the side of the cups, and for a predetermined distance on the inner face of the heads by the flanges (1 (1 on the gluecups. A

The actuating mechanism 6 consists of a driving-shaft 6, supported in the bearings e 6 secured to the floor. On the outer end. of the shaft e is secured the pulley e and on the inner end the bevel gear-pinion e. The. shaft e is supported in a bearing e, secured to the floor at right angles to the bearings 6 e On the inner end of the shaft (2 is secured a disk e ,ha'ving the bevel-gear e on its backmeshing with the bevel gearpinion e and the eccentric-pin e on its face. The pulley e and the disk 6 revolve in the direction of the arrows, as shown in Fig. 1'. A rock-shaft e f is supported in the bearings a a ,and to the inner end of the rock-shaft is secured an arm a, which in turn is pivotally secured at its free end to an actuatingarm 6 having a notch e in its lower edge for the pin a". On the rock-shaft e is secured a bell-crank lever e, the outer arm of which is pivotally secured to the lover end of the connecting-link e wlzich in turn is pivotally secured at its upper end to the outer arm of the bell-crank lever e secured to a rock-shaft a", supported in the bearings a a on the frame. The upper arm of the bell-crank lever e is pivotally secured to a connecting-arm 6 which in turn is pivotally secured to a cross-shaft 6", connected to lugs on the under side of the slides a c of the feed mechanism 0, as shown in broken lines in Fig. 1 and Fig. 2 and in full lines in Fig. 5.

The lower arm of the bell-crank levere is of which are pivotally secured the connectinglinks e e, which in turn are pivotally secured to the lower ends of the arms d d of the gluing mechanism d. By this construcsecured a facelate h, havin tion the feed mechanism a and the gluing mechanism d are operated when .the a ctuating arm a" is released and the pin e engages with the notch e in the. actuating-arm. The glue-pot) is in the form of an open-top metal box, and the gas or steam jet g g is placed under the glue-pot to keep the glue at the re uired temperature.

The lead-stock h of the assembling'mechanism consists of an inverted- U-shaped frame secured tothe bed a? and having the bearings h h for as indle h A. pulley k is secured to the spind e between the bearings h h, and on the inner end of the spindle is the central pin hfladapte to enterthe' ole m in a spool-head and the hole m in a spool-cylinder,

and the chisel-shaped points h h adapted to engage with a spool-headand revolve thesame.

I The tail-stock'i of the assembling mechanism is adjustably secured to the bed a) on a fastening-bolt '5 in the usual way-and as a longitudinal boreyi in which is a spline '5 as shown in broken lines in Fig. 1. A reciprocatingspindle '5 having the longitudinal groove t extends through the bore i in the tail-stock. The spline i en-' gaging with the groove '5 in the spindle prevents the rotation of thespindle. On the inner end of the spindle t is secured a faceplate '5, having a central pin '5 on a line with the pin it for a spool-head and cylinder and the chisel-shaped points i i adapted to engage with the bobbin-head and prevent rotation of the head. The bifurcated fitting 'i" is secured to the outer end of the spindle '1' by the set-nut i)", as shown in Fig. 1. The tailstock'i is adjustable lengthwise on the bed 0, for different len ths of bobbins.

The release-arm its upper end to the spindle 'i". by the set-bolt k and extends downward through a slot in the bed. The lower L-shaped end 1: of the release-arm extends toward the front of the machine under the outer end of the actuatingarm a", supporting the lever in its normal or inoperative position, as shown in Figs. 1 and 4. The operating-lever l is pivotally'secured adjacent its inner end to the fitting 7/ on the spindle i and at its inner end to the connecting-link Z, which in turn is pivotally secured to the bracket i on the tail-stock i. The operating-lever extends toward the front of the machine over the top a in a convenient position for the operator, as shown in Fig. 2.

In the operation of my improved spool gluing and assembling machine the operator removes the two glued bobbin-heads m mx (shown in broken lines in Fig. 2 from the the rotating of the face-plate h in the direction .of the arrow on the pulley h as shown in Fig.1. As the operatinglever Z is .moved forward the L-shaped ends k on the releasearm 7c moves forward to release the actuating-arm e The eccentric-pin e on the disk e moving in the direction of the arrow, as shown in Fig. 1, now engages with the actuating-arm e through the notch e in' the arm and through the arme, the bell-crank lever e3, the link e, the bell-crank lever e and the arm e, and the cross-shaft e actuates to operate the feed-slides c c of the feed mechanism 0 to deliver two spool-headsto the gluing mechanism and, simultaneously through the connecting-bar e the arm a, the armsc? e, and the connecting-linksle c and the arms (1 d actuate to operate the gluin mechanism (1 to glue the screw-threaded ho es m m in the spool-heads, thus feeding, gluing, and assembling a spool in one operation .of the operatin -lever, Z. The s eed of the actuating mec anism e is less tlian the time required to operate the assembling mechanism by the operating-lever Z. The return movement-of the operating-lever [brings the L-shaped ends k of the releasevarm is under the actuating-arm a, holding the actuating-arm in its inoperative position until the next forward 'movement of the operating-lever.

Having thus described my invention, I
